Kayaba twin chambers??

[ScottyR]

The tubes from the 48m KYBs and the 48mm Sachs are exactly the same dimensions so they should fit as long as you have Sachs clamps. The Zoke tubes are smaller and the KYBs will not fit.

Scott,

Are the Yamaha and Husky KYBs the same size?

hallam76,

Could we narrow this down to year and model Yamaha YZ250, YZ250F, etc.) ?

The later yz and yzf forks I know are the right diameter, I am looking at 2007 YZF 250 forks.
The Husky KYB for are different they are the open cartridge and I am not sure if they are teh same diameter.

The TC 48mm KYBs that Husky uses are 2007 era forks.

The TEs use open chambers that are the same as current Yamaha WRs.

The TC and TXC use closed chambers.

Do you guys know if the open chamber KYBs found on the Yam WRs have the same upper tube sizes as the AOS and SSS on the YZs?

The 48mms are the same.

I run 47mm Showas on my 48mm sachs triple clamps (with 0.5mm shimming), with a Honda front wheel too.

The WR and YZ stuff 48mm forks I checked, were too large even though they were 48mm lowers like sachs.

Maybe the 2011 CRF450 48mm showas fit easily.

260mm disc diametres mean the jap caliper mounts won't line up to gasser wheels.

Hi!

Check this picture from Mika Ahola's blogspot..

All top racers (Botturi, etc) use KYB SSS twin chambers on their 2011 Gasers... Checking carefully the picture it seems that they use a Yamaha wheel too (the shape of the disc...)

My wish in another post seems that it will come true maybe in the 2012 models..? But, why then the factory offers the new Marzocchi twin chamber in the 2011 Race models? It is quite confusing... The simplest thing is to offer all models with KYB SSS (different settings for Race model...) and Ohlins TTX on the Nambotin and Cervantes Replicas.... Unless Sachs and Marzocchi forks are cheaper to buy...

The Japaneese big four have a huge buying advantage with the high numbers. The small guys have to work within their price point with the smaller mfgs.
